Granted, other methods can work, you REALLY want a smooth flat finish. Otherwise, you can wipe out a cam lobe, then, you start all over.......for many valves......

I am not a machinist, I'm a decent "metal hacker". I have a few years working on my own and in shops.
I know when to "MacGuyver" and when to do it right.
id think you would grind the underside where it touches the valve stem.
